1938 Groma Modell N

Serial #200356

This Groma is one of the earliest: the first number for Groma is 200000, so this could be number 356!
Also a surprise: the cover of this two-tone dark burgundy machine is bakelite. Makes me wonder: do all the burgundy Groma's have a bakelite cover?
Typeface: Ro 1, spacing 2.6 mm "Kleine Druckschrift - Pica". German keyboard.
